lhisinvention `relates to railway. cars, and

more particularly to wall structures therefor in'which the side wallsA are designed to'carry apart of the load to the body'bolsters offthe car and the end walls are designed to carry f a partv of the. loadl to the sidewalls andV to thedraft sills, and the vobject of theinvention is to provide a girder-wall fora railway car comprising a metallicplate (or plates) 1() having certain elements formed integral therein, thereby eliminating the necessity of y y r tweenv thecreinforcing; ribsr so as to mutually.y

formingV and fabricating such elements,v .thus

reducing the number of parts and alsoreduc'-l ing the Aweight of the finished car wall.y In the drawings: Y f

-Figs 1 and 2 show `my invention used inr the side wall of a.. railwayr boXcar whereinv the side plate 2 andV side sill fof'the car' are theupp'er and lower 4chords respectively of V- the truss, and the '.web platesl Llform the `retaining wallV ofthe car. The integrally formed struts 5 of the truss form the transomw post, intermediate postand doorpost respectively of the car, and the tieplates 6 or ten,-

sion members of the truss form. the usual,tief

rods between the sill and plate of'the car.

These tie plates 6are preferably 'secured v(7) to the web plates 4 adjacent the sill and plate respectively. -In this-arrangement the web.

plates Anot 'only form: the 'retaining ywall `of the'car but also -constitute the gusset `structure of the truss between the Vstruts 5 andthe *Y chords and also between the tension members G'andth chords. lhef.reinforcing ribs Sfre-f .l v .45 `tard the bucklingtendency .of the .webl plates as gussets of thetrusssandalso'reinforce them` i to performthefpfunctions ,of the `retaining wall 'of the car.v` `These ribs 8 may extend diyagon'ally orhorizontally but preferably eX- U tend vertically-and parallel vto'the struts', as 5o shown, yand V.preferably extend the distance a between the chords and terminate within the web plates adjacent the chords so? astotrans-V mit any horizontal'load imposed upon them by the lading'to the chords.
